It's a very good phone, but i only have 1 question. So there are 3 holes, the first from up to down, the middle one for SIM and the last one for the memory card. What is the purpose/role of the first hole?

I've been using this phablet for many months now (HTC Desire 820 single sim 4G). Not even once did I ever get any single problem, this phone is simply awesome and totally reliable. I've used it under different weather conditions, the Desire simply keeps going, on and on. Maybe the battery is a tad short of a day's use when using 4G or 3G, but all and all, this is one of the very best phones I've owned so far. After so many months of trouble-free use, I'd readily recommend it, and on top of that, it's good looking too. Now I'm only waiting for the OS promised upgrade from HTC.

sree, 08 Oct 2015Hwz d update working?? Anyone plzzzIt's working good. Maybe after installing lollipop update some of you may find the phone lagging. The sure shot remedy is doing a factory reset then using it.

Qamer, 07 Oct 2015I have a problem with my cell phone when I used my cell on charging position my mobile has not... moreThis is very normal. The charging rate is lower than discharging rate while using. So don't use while charging.

Been using Android 6.0 on Desire 820 for some hours.
The battery life has definitely improved.
Overall phone performance is way better than before.
Most importantly, during my extensive exploration of the new OS, it did not lag/freeze/hang even once.

Yea finally got lollipop update for d820 i don't have any problems in using this phone and i have been using it since 9 months,no lags,no battery problem everything is working fine much better than samsung A7,xperia Z1 and many more smartphones
